Bill Gross, the manager of the biggest bond fund in the world, has forgotten more about bonds than most of us will ever learn. That is why the big move that PIMCO has just made is so unsettling. At one time PIMCO held more U.S. government debt than any other bond fund on the globe, but now news has come out that they have gotten rid of all their U.S. government-related securities. So should we be alarmed? For months Gross has been warning that the bull market in bonds is coming to an end, and now it looks like he is putting his words into action.s Gross has often publicly decried the rampant government spending that has been going on over the last several years, and apparently he has seen enough. He is taking his ball and he is going home. This really is a stunning move by PIMCO. Gross must really believe that something fundamental has shifted. Gross didn't get to where he is today by being stupid. But so far world financial markets are taking this news in stride. Nobody seems all that alarmed that the largest bond fund in the world has dumped all of their U.S. Treasuries. But with world financial markets in such a state of chaos right now, shouldn't we all take note when one of the biggest players in the game makes such a bold move?
